Tenants
Am I paying too much rent?
Your rent against every similar home registered with the RTB when it was set, and what the law lets you do about it.
1
The register, at the right date
Similar homes in your electoral area that were let around the time your rent was set. The law tests the rent then, not now.
2
A verdict, not a hunch
Above every similar home, above most but inside the range, or within the market. Each has a different next step.
3
The words and the proof
Every comparable with its RT number, what to say to the landlord, the RTB dispute type, and the notice checked if you got one.
The verdict is free. The report: €14.99 free until 1 October. A person checks each one, so it comes by email within one to two working days.
Questions
My rent is above the others. Can I get it reduced?
The law says rent may not be set above market rent, at the start of a tenancy and at every review (Residential Tenancies Act 2004, section 19). Market rent is what similar homes actually let for, a range rather than one number. If your rent sits above that range, you can ask the landlord to lower it and, failing that, refer a dispute to the RTB under 'rent more than market rate'. The report gives you the figures, the RT numbers and the words.
Why does the date I moved in matter?
Because the test is applied at the date the rent was set. We look at similar homes registered around that date, not today's market. A rent that looked steep two years ago may look ordinary now, and the other way round.
The landlord says everyone around here pays more.
The register shows two groups: new tenancies, agreed recently at market rates, and continuing tenancies whose rent has been capped for years. Your landlord may be quoting the first while you are in the second. Even if the market is higher, your increase is still limited to 2% or inflation a year from the last time the rent was set, with 90 days notice on the RTB form.
I just moved in. Could the rent have been set too high?
For tenancies starting from 1 March 2026 the landlord must give you a rent setting notice with the previous rent, the date it was set and three comparable tenancies from the register. Market rent is only allowed if the last tenant left by choice, was put out for breach or arrears or because the home no longer suited them, the home stood empty for two years, or it was substantially changed; otherwise the new rent is the old one plus 2% or inflation. If you got no notice, or the figures do not add up, the RTB can order a repayment.
Do I need the RT number of my own tenancy?
No. It is on the RTB confirmation letter your landlord received. If you have it, we use it to leave your own tenancy out of the comparison; otherwise we do that by rent and date.
